查看此处Execute Ant From Your Application 看看这个例子:

      Project project = new Project();
      project.init();
      DefaultLogger logger = new DefaultLogger();
      logger.setMessageOutputLevel(Project.MSG_INFO);
      logger.setErrorPrintStream(System.err);
      logger.setOutputPrintStream(System.out);
      project.addBuildListener(logger);

      File buildFile = new File("buildhtml.xml");
      ProjectHelper.configureProject(project, buildFile);
      project.setProperty("ant.file", buildFile.getAbsolutePath());
      project.setProperty("item", "ant");
      project.setProperty("inputdir", "src/items/ant");
      project.setProperty("outputdir", "build/items/ant");
      project.setProperty("graphics.prefix", "../../");
      try {
         project.executeTarget("checkifuptodate");
      } catch(Exception e) {System.err.println(e.getMessage());}
      // rest of program goes here

这是比调用 Runtime.exec 更好的解决方案
